Patent JP-S63144270-A (JP)
Title: Screening method
Inventor: NAGAO YUTAKA
IPC: G01R31/30
Filed: 1986-12-08
Abstract: PURPOSE:To improve the detection sensitivity of a defective by conducting a dynamic bias test wherein a clock or pattern input signal is applied and a static bias test wherein those signals are not inputted in a series of test periods. CONSTITUTION:While neither of the clock input signal 1 and pattern input signal 2 is applied, the static bias test is conducted first in a determined period (much longer than the longest period T of the clock or pattern input signal) to integrate impurities which cause a defect in an IC. Consequently, the defective IC is deteriorated. Then the clock signal 1 or pattern input signal 2 is applied for the determined period to conduct the dynamic bias test. Consequently, an IC having a defect in wiring, etc., is deteriorated. Finally, various measurements of ICs are taken and deteriorated ICs are rejected as defectives.

IPC: H01J11/42
Filed: 1990-10-29
Abstract: PURPOSE:To enhance display brightness and visual confirmability by a pair of electrode discharging in an electric discharge area (ES), which includes a light emission area (EH) provided with a fluorescent material and expands outside the EH. CONSTITUTION:Belt-shaped electric discharge parts 23a, 24a face one another and determins their lengths and numbers so that an electric discharge area ES may include an area EH and its outside. That is, the electric discharge part 23a, 24a, are installed so that the area ES may be about 1.5 times as large as the area EH in diameter. In order to display a PDP1, a prescribed voltage is applied across electrodes 23, 24, to induce an electric discharge in the area ES so as to produce ultravioled rays UV, which excite a fluorescent material 18 for light emission. In this case, the ultraviolet rays UV are in part diverged outside the area EH, but other ultraviolet rays are produced on the periphery of the area ES and applied to the fluorescent material 18 to compensate for the divergence loss. This increases the ultraviolet rays applied to the area EH to enhance the brightness of the area EH.

IPC: B41J2/175
Filed: 1999-10-15
Abstract: PROBLEM TO BE SOLVED: To accurately manage a time limit for usage of an ink cartridge even when the ink cartridge is used in different printers. SOLUTION: When an ink cartridge 5 is loaded to a printer 1, the printer records a loaded date/time to its EEPROM 17. Before, for example, the ink cartridge 5 is replaced, a difference between the present date/time and the date/time when the ink cartridge is loaded is calculated and the value is added to the lapse of time that is already recorded in an EEPROM 11 of the ink cartridge 5 and has elapsed from when the package of the ink cartridge is broken, and then the added lapse of time is written over the EEPROM 11 of the ink cartridge 5. The updated lapse of time of the ink cartridge 5 is judged at any time by a time limit judging section 21. When the lapse of time exceeds a time limit for usage, for example, 6 months from the breaking of the package, a user is notified of the fact via user interface of the printer 1 or a host device 3.

Title: Abnormal voltage detector/controller
Inventor: HATAKEYAMA YOSHIHIRO
IPC: H02H3/20
Filed: 1991-11-11
Abstract: PURPOSE:To make it possible to trip a control object upon detection of an overvoltage by a constitution wherein an electromagnetic coil is de-energized to disable closing of the control object when the control voltage exceeds a maximum allowable level whereas the electromagnetic coil is energized to enable reclosing of the control object when the control voltage drops down to a resetting level. CONSTITUTION:When a control voltage Vo increases over a maximum allowable level, an overvoltage appears at a voltage dividing point C and a first voltage detector 11 produces an OFF signal T1 of logic 1. The OFF signal T1 is fed to an OR gate 13 to produce a trip signal T for tripping a drive circuit 3 thus de-energizing an electromagnetic coil 4 and disabling closing of a circuit breaker. When the control voltage drops under light load, a potential having resetting level appears at the voltage dividing point D and a second voltage detector 12 produces an output signal of logic 0 thus stopping an OFF signal T2. Consequently, the trip signal T goes L to turn the driving circuit 3 ON thus energizing the electromagnetic coil 4 and enabling reclosing.

Abstract: PURPOSE:To remove a vibration at the time of acceleration without varying the response of a PLL control circuit itself by switching an input to phase difference detecting means between a first signal and a second signal by signal switching means according to the value of the frequency of the first signal. CONSTITUTION:A changeover switch 4 receives a command from a switch switching command generator 3 to switch an input to a phase comparator 5.
